Debbie Claybourne and Judith Burton are best friends who thought they knew everything about each other - except that Debbie had no idea Judith is an international assassin.

When a mysterious figure emerges from Judith's past and a hit goes horribly wrong, both of their worlds are turned upside down, forcing them to go on the run together.

It's a race against time and a road trip across Europe, with law enforcement, highly trained assassins, and some very dangerous criminals on their heels.
